The average dive in Cancun is around 40 feet but open-water dives can go as deep as 85 feet. Drift diving is the norm here and the big attractions are the coral reefs where hundreds of fish parade past the diver’s mask. The coral reefs off the coast of Cancun and nearby Cozumel are sheer bliss for lovers of the underwater world and are the best places to dive in the Mexican Caribbean. Whether you’re a beginner or advanced diver, Cancun has a dive for you.
Diving in the cenotes (sinkholes) of the Yucatan Peninsula and finding cool, crystal-clear water (visibility of 200 feet) is a unique experience found only in this part of Mexico. Experienced cave divers who dip in and out of the intricate maze of underwater caverns find it to be a thrill beyond compare. For the truly adventurous (intermediate and expert divers only), Cuevas de los Tiburones (cave of the sharks) off the coast of nearby Isla Mujeres may provide a glimpse of these dozing predators. For beginning divers, Cancun provides a great show of tropical fish and lots of coral in safe, shallow waters.
There is a whole host of marinas and dive schools in Cancun that offer dive lessons, certification, and guided tours to the various diving spots in the area. (for a directory of marinas, see Marinas & Sports Centers later in this section.) An excursion to dive in Cozumel or in the cenotes will be an amazing experience that you can enjoy staying at Cancun. A PADI openwater certification course takes three to four days. All dive shops are staffed with PADI certified dive masters and bilingual scuba instructors. Cancun also has two hyperbaric chambers located downtown.
